Title: Variable capacity diode and manufacturing thereof
Inventor: NAKASHIMA MASAKI
IPC: H01L29/93
Filed: 1978-08-23
Abstract: PURPOSE: To reduce noises when variable capacity diode is used in electronic tuning circuits for TV sets, radio receivers and others through a given capacity variation rate against voltage, by defining the inpurity ion concentration profile of variable capacity diode so as to be able to obtain the hyper abrupt step junction.  
     CONSTITUTION: Epitaxial growth to from an n - -type layer with a thickness of 0∼X 1  and the inpurity ion concentration of NEP is developed on an n + -type Si substrate. Into this n - -type layer, an n-type P is added by diffusion or ion-injection so as for its surface concentration of CS, and its depth to become relatively low and deep respectively, thereby forming an n - -type layer shown in the N 1  distribution. Afterwards, an n + -type region shown in the distribution N 2  is formed by diffusing or ion-injecting As which also ia an n-type so as for its surface concentration CS 2  and its depth to become, this time, relatively high as well as shallow respectively. Then, a p + -type layer is formed only on the surface layer by diffusing p-type B, resulting in a hyper abrupt step junction. This enables the reduction of noises in the tuning circuits and further a receiving frequency scale to become regular.

Title: Index production system for optical disk
Inventor: KUMAGAI KAZUO
IPC: G11B7/26
Filed: 1983-06-09
Abstract: PURPOSE:To position an optical head at a prescribed revolving position and to produce an index mark by using a revolving position detecting means which revolves the optical disk and detects the prescribed revolving position of the disk, and a means which sets the optical head at the prescribed revolving position. CONSTITUTION:The optical axis of an optical head which is set on a carriage 14 is fixed, and a cross pulse introduced by crossing to a track is sent to an eccentricity measuring circuit 4 from a photodetector which detects the reflected light of the optical head. The circuit 4 resets the timing pulse to a tachocounter 9 via an OR circuit 7 in the timing which produces the minimum variation degree of eccentricity. The counter 9 starts counting and resets the number of times, of counting at the minimum point of the variation degree due to the eccentricity of an optical disk. Then the counter 9 restarts counting. Such action of the counter 9 is repetitively carried out. When an index production signal is fed to the circuit 4 from a terminal B, the timing pulse is sent to a flip-flop 6 and to a brake control part 5. The stop position of a motor is controlled by the number of decoders 8, and the number of decoders 8 is set at the maximum value or a level near zero of the counter 9.

Title: Method and device for measuring characteristic of magnetron
Inventor: YOKOTA YOSHIROU
IPC: H01J25/50
Filed: 1979-08-15
Abstract: PURPOSE: To automatically discriminate between the right and wrong of the wave form of a plate current, by sampling the plate current, winding the skirt of a wave form signal resulting from the sampling and by determining the difference in area as to the winded portion.  
     CONSTITUTION: In a plate current detection circuit 1, a plate current is sampled by a pickup resistor. The sampled plate current is applied to an integrator and comparator 3 by opening and closing an analogue switch 2. A trigger signal synchronized with a wave form signal by a power synchronizing signal circuit 5 is supplied to a wind pulse generator 6 by the analogue switch 2. The integrator and comparator 3 integrates the to-be-integrated portion of the wave form of the plate current applied from the analogue switch 2 and calculates a DC voltage corresponding to the integrated area. A voltage corresponding to the limit value for a wrong wave form is separately set. The voltage is compared with the value integrated by the integrator and comparator 3. When the limit value is exceeded, a defect signal is indicated. It can thus automatically be discriminated whether the wave form of the plate current is right or wrong.

IPC: H04N1/403
Filed: 1995-04-27
Abstract: PURPOSE: To prevent deterioration in image quality by setting initially error data less than a threshold level to each picture element position of an error storage means prior to starting binarization or multi-value processing so as to quicken incidence of a black (white) picture element at a low (high) density area of an image. CONSTITUTION: An error setting section 17 sets initially a prescribed value to each picture element position storing accumulatingly a weight error in an error storage circuit 16 prior to start of binarization processing. When a uniform input image signal Si is given to a correction circuit 11 in this state, the circuit 11 at first adds an image correction signal Sc from the circuit 16 to the signal Si for the correction to provide an output of a correction signal Sic. The signal Sic is compared with a threshold level Th at a binarization circuit 12 and the circuit 12 provides an output of a binarized image signal So. On the other hand, a binarization error calculation circuit 13 calculates the difference between the signals Sic and So and provides it as a binarization error signal Ser to a weight error calculation circuit 14.  The circuit 14 calculates a weight error based on a weight coefficient of a noted picture element with respect to peripheral picture elements and applies accumulation processing to the level set initially at the picture element position of the circuit 16.
